It will affect you, since you are reporting (a) missing method errors and (b) you want to clear your work directory, presumably to remove .jsp -> .java -> .class files to trigger recompilation of all of those. I would pause and NOT deploy 9.0.96 because recompilation will stop the app from throwing those missing-method errors, but some tags might actually not behave properly. > We separate our CATALINA_HOME from our CATALINA_BASE, so app teams just need > to restart their instance after the upgrade. > > Doing this in Linux/Unix/MAC, is easier as we can do this with the setenv.sh > script or in the startup or shutdown scripts.

As to your question about procrun running a script before it launches Tomcat, I think the short answer is "no" but I do have an idea for you. Create a new service called Tomcat-cleanup, make it a simply BAT/PS script that cleans-out that directory, and make it a startup dependency of the real Tomcat service. [Mcalexander, Jon J.] Thanks for this information Chris. I can probably create this dependency, but then I wouldn’t want it to be running all the time, will having it as a dependency start said service? I could use Procrun to probably do this service, but then how do I tell it to run and then stop?
